Purist, I know I am nagging but I talked to the dealership and the oil they use for the 370z is made by Nissan. They also use it on all their infinities. I'll get a pic of the bottle soon and post. It says 5w40, API SM/CF, and ACEA-A3/B4. The mobil 1 says API SM (no CF), ACEA-A3/B3 and ACEA-A3/B3. Now that you know where I live would you still recommend the 5w40 over the 0w40? The dealership claims the oil is from Nissan. Perhaps because of the different weight it is not easer based? What are your thoughts?
